关于模数转换The ADC0808M is a monolithic CMOS device with
an 8-channel multiplexer, an 8-bit analog-to-digital
(A/D) converter, and microprocessor-compatible
control logic. The 8-channel multiplexer can be
controlled by a microprocessor through a 3-bit
address decoder with address load to select any
one of eight single-ended analog switches
connected directly to the comparator. The 8-bit
A/D converter uses the successive-approximation
conversion technique featuring a high-impedance
threshold detector, a switched capacitor array, a
sample-and-hold, and a successive- approximation register (SAR). Detailed information on
interfacing to most popular microprocessors is
readily available from the factory
